河南烟区土壤钾素含量与分布

Content and Distribution of Potassium in Soils of Henan Tobacco Growing Areas

  • 摘要: 对河南烟区2 116个土样钾素含量进行了分析,结果表明:河南省土壤速效钾含量平均为188.88mg/kg,全钾含量平均为2.28%。从不同烟区来看,土壤速效钾含量状况排序为:豫西 > 豫东 > 豫西南 > 豫南 > 豫中;全钾含量排序为:豫东 > 豫西 > 豫中 > 豫南 > 豫西南。从主要植烟土壤类型看,速效钾含量排序为:红粘土 > 潮土 > 褐土 > 砂姜黑土 > 黄褐土 > 黄棕壤;全钾含量排序为:黄棕壤 > 红粘土 > 潮土 > 褐土 > 黄褐土 > 砂姜黑土。根据河南烟区植烟土壤钾素含量及分布特点,提出了相应的施肥措施。

     

    Abstract: The contents of potassium in 2116 soil samples collected from tobacco growing areas in Henan Province were analyzed. The results showed that the average contents of rapidly available K and total K were 188.88 mg/kg and 2.28% respectively. The tobacco growing areas in order of contents of rapidly available K were west Henan > east Henan > southwest Henan > south Henan > middle Henan and in order of total K were east Henan > west Henan > middle Henan > south Henan > southwest Henan. The major types of tobacco soil in order of contents of rapidly available K were red clay > fluvo-aquic soil > cinnamon soil > sajong black soil > yellow cinnamon soil > yellow brown earth and in order of total K were yellow brown earth > red clay > fluvo-aquic soil > cinnamon soil > yellow cinnamon soil > sajong black soil. The suitable fertilization method was recommended based on the characteristics of potassium content and distribution of soil in Henan tobacco growing areas.
